SANTA CLARA, Calif. -- Last week, Greg Roman blamed himself for the struggles of the San Francisco 49ers' offense.
This week, after the unit slumped for a second straight game, the offensive coordinator predicted things are about to change. Even though his unit has scored just two touchdowns and accounted for 22 first downs in the past two games, Roman thinks the 49ers' offense is about to "pop."
"Well, I think it's a function really of making a few more plays, really," Roman said Friday. "You look at that game, we make one or two more plays, we win the game. The week before, we make one or two more plays, we win the game. We're always striving for improvement and we're certainly not a finished product. So, I think those opportunities are out there and the roof's going to blow off. It's going to pop. It's coming. We keep working like we're working and it will come."
The offense's next opportunity is Monday night at Washington.
In other 49ers news:
Kyle Williams, cut by the 49ers and claimed by the Chiefs last week, tore his ACL and is out for the season. He also tore his knee with the 49ers a year ago. The news got around the 49ers' locker room Friday that Williams, who was popular among his 49ers' teammates, was injured.
"It's terrible," said running back LaMichael James, who took Williams' spot as the 49ers' punt returner.
The San Francisco Chronicle reported that Tampa Bay safety Dashon Goldson, who is suspended this week for an illegal hit, visited the 49ers' facility Friday. He left the 49ers as a free agent this offseason. The 49ers play at Tampa Bay next month.
Defensive coordinator Vic Fangio admitted he wished the 49ers played the Redskins earlier in the season because quarterback Robert Griffin III continues to get better mobility as he recovers from knee surgery.
Fangio also said rookie defensive lineman Tank Carradine continues to work his way back from a torn ACL. He has been inactive the past two games since he was put on the 53-man roster. It sounds like he still may need a little time to adjust.
Safety Eric Reid said teammates were thrilled for running back Marcus Lattimore, a fellow rookie who practices for the first time Thursday. Lattimore will practice for the next three weeks, but he is not expected to play until next season. The fourth-round pick suffered a horrific knee injury at South Carolina in 2012.
"I'm happy for him," Reid said. "He looked good."
