Cornerback Mike Rumph is no longer with the 49ers.

The 49ers on Monday announced a trade that sends Rumph to the Redskins for wide receiver Taylor Jacobs, a second-round draft pick in 2003. Jacobs caught 11 passes for 100 yards and no TDs last season for the Redskins in 15 games.

Rumph struggled in the exhibition opener Friday night, missing four tackles. He probably would not have won a roster spot with the 49ers this season.

"Mike's been a very good 49er," coach Mike Nolan said. "He's been good since we've been here both on and off the field. He's been extremely active in the community. He's done everything we've asked on the field."

Did you see those nifty patches the 49ers are wearing on their shoulder pads to commemorate the franchise's 60^th season?

It's a nice touch to the team's uniform. But it also got me wondering about who's doing the math.

The logo reads: "60 Seasons," and it has "1946-2006" inscribed below.

There's only one problem with all this. This is actually the 49ers' 61^st season.

With my investigative skills working overtime, I went to 49ers head PR guy Aaron Salkin to ask about this all-important issue. He checked with the marketing folks and reported back to me that the 49ers went through the NFL office before coming up with this logo. In fact, the Browns have a similar emblem for this season, too.

But the Browns don't declare 60 seasons or 60 years or a 60^th anniversary. They just have the number "60." They leave the rest up to the imagination.

The 49ers, however, spell it out. This is the 60^th season of 49ers football - even though it's really No. 61. Maybe this 61 deserves an asterisk, too.

This whole issue reminds me of the nasty emails I received three years ago when the 49ers finished with a 7-9 record. I stated that the 49ers finished two games under .500. Any reasonable person would agree that the 49ers won two fewer games than they lost. However, some dude who flouted his Mensa credentials told me I was wrong. He said the 49ers finished one game under .500 because if they'd won one of the games they lost, they would've been .500. Of course, that's true, but the idea is, how many games in a row would you have to win to get back to .500. After our email conversations -- in which trying to communicate with the guy was like talking to a parking meter -- I ended up feeling that the clown from Mensa wasn't so smart after all.

The 49ers signed first-year LB Sarth Benoit (Southern Connecticut State). He ended last season on the Lions practice squad.

OL Adam Snyder sat out practice to undergo an MRI on his left elbow, which he injured during practice yesterday. RB Maurice Hicks also had an MRI on an abdominal strain. No word yet on the results of those examinations. CB B.J. Tucker, LB T.J. Slaughter, CB Derrick Johnson, and C Ben Sobieski did not practice. RB Kevan Barlow returned to practice, as did DL Jerry DeLoach.

The 49ers held their morning padded practice on their new Sportexe artificial surface. The play of the day occurred when QB Trent Dilfer was intercepted as he tried to get a pass into Antonio Bryant across the middle. LB Jim Maxwell picked off the pass, then tossed a lateral to OLB Parys Haralson, who then lateraled to Keith Lewis, who took it down the right sideline for a touchdown. - QB Alex Smith continues to practice throwing on the move. But on one play, as he rolled right, CB Shawntae Spencer broke in front of Bryan Gilmore for the interception on the sideline. On another play from the 5-yard line, Smith rolled left and threw across his body to TE Vernon Davis, who made the catch at the goal line. - Nothing new here, but Smith and WR Antonio Bryant hooked up on a couple deep plays. In an 11-on-11 drill, Bryant got behind FS Mike Adams. On a 7-on-7 session, Bryant caught a 15-yard TD pass on a corner route, beating CB Sammy Davis and FS Mark Roman.

K Luis Berlanga looks like he might finally arrive in town from Mexico. He has been unable to get into the country because of paperwork delays. The 49ers would like for him to kick in at least one exhibition game.

The 49ers have only a special-teams practice scheduled for the afternoon. Coach Mike Nolan said the team will continue to have training-camp style practices tomorrow and Wednesday. But Friday, Saturday and Sunday, they'll proceed as if they're in the season. In other words, they'll spend three days doing a little game-planning for the Raiders just to give everybody a taste of how things will be conducted during the regular season.
