Football: Two 49ers with concussions could be done

SANTA CLARA, Calif. - Two San Francisco 49ers defenders with concussions could be done for the season.

Safety Michael Lewis sustained his third concussion of the season during Sunday's 45-10 loss to Atlanta and was to have further testing during the off week. Linebacker Jeff Ulbrich, who suffered a concussion on the opening kickoff against St. Louis on Oct. 4, is scheduled to be seen by a neurologist on Wednesday.

It will be the first time the 10th-year player has been examined by a neurologist and Ulbrich said Monday he's not ruling out retirement after sustaining more concussions during his career than he can count.

"I don't know (how many)," Ulbrich said. "I don't even really know what a concussion is. They ask me if it's like seeing stars, but every linebacker in the NFL has five or six of those a game."

Lewis, who sustained two concussions during an 11-day span in the preseason, could be sidelined for a prolonged period though coach Mike Singletary didn't want to speculate Monday.

Ulbrich said he's dealing with his health "day to day" and isn't thinking about his football career beyond today's exam. After that he might be forced to make a big decision.

He acknowledged he's at a point in his life when he needs to think about his long-term health, future and family.

"I have to take all those things into consideration," Ulbrich said.
