49ers WR Michael Crabtree vs. Bears CB Charles TillmanTale of the tape
Crabtree (15): 6-foot-1, 214 pounds, fourth season, Texas Tech
Tillman (33): 6-foot-2, 198 pounds, 10th season, Louisiana-LafayetteWhen the Chicago Bears' defense is on the field, their own offensive production does not slow down.The Bears have scored eight touchdowns on defense this season. In a game that is set to feature backup quarterbacks Colin Kaepernick and Jason Campbell, this game could turn on turnovers.NEWS: Smith denied final clearance to play
And nobody generates turnovers as well as Bears cornerback Charles Tillman. He has scored two touchdowns on defense. Tillman has intercepted two passes and forced an amazing seven fumbles."I've never seen anybody do it better, so that's pretty good," 49ers offensive coordinator Greg Roman said. "And every time he does it, it seems he might not get it out, but he's definitely close to getting it out or the person carrying the ball is extremely aware of his presence."The Bears generally match up their cornerbacks to play a specific opponent, and it seems like a reasonable expectation that Tillman will be on 49ers top wide receiver Michael Crabtree most of Monday night's game.Crabtree has clearly emerged into the 49ers' top pass-catching target this season. He leads the 49ers with 44 receptions for 510 yards and four touchdowns.Tight end Vernon Davis has seen his production in the 49ers' passing offense diminish over the past four games. During that time, Davis has caught just nine passes for 101 yards and no touchdowns. In that same period, Crabtree had 17 catches for 199 yards and three touchdowns.With Crabtree getting his hands on the ball more, it means he'll have to secure the ball after the catch against Tillman and the rest of the turnover-producing Bears defense."You definitely teach ball security," Roman said. "I mean, there's a technique to carrying a football."

Ex-49ers RB Gore moves to No. 8 on all-time list

Frank Gore continues to move up the list of the top rushers in NFL history.

Gore, the 49ers’ all-time leading ground-gainer, picked up 79 yards on 20 rushing attempts Monday night in the Indianapolis Colts’ 41-10 victory over the New York Jets.

Gore moved past Tony Dorsett and into eighth place on the NFL’s all-time list with 12,789 yards. Next up is Eric Dickerson at No. 7 with 13,259 yards.

The only retired player in the top 11 all-time rushers who is not in the Pro Football Hall of Fame is LaDainian Tomlinson. He is eligible for the induction for the first time in 2017. The only other running back in the top 15 who is not in the Hall of Fame is Edgerrin James at No. 12.

In 10 seasons with the 49ers, Gore gained a club-record 11,073 yards. In 28 games with the Colts, Gore has 1,716 yards. After coming up just 33 yards short of the 1,000-yard mark in his first year in Indianapolis, Gore needs 251 yards in the final four games for the ninth 1,000-yard season of his 12-year career.

Seahawks lose All-Pro S Earl Thomas for season

Seahawks lose All-Pro S Earl Thomas for season

RENTON, Wash. -- The Seattle Seahawks will be without safety Earl Thomas for the rest of the season due to his broken lower left leg, no matter how far the team advances in the playoffs.

Coach Pete Carroll said Monday that further examination determined Thomas' fractured left tibia will require a recovery time that does not allow for the possibility of a return during the 2016 season. Carroll said after Sunday's 40-7 win over Carolina that Thomas' injury usually takes a minimum of six weeks of recovery time.

It's the first major injury of Thomas' career. He played 106 straight games before missing Seattle's loss at Tampa Bay last week with a hamstring injury. He quickly recovered to play against the Panthers, but was hurt in a second-quarter collision with teammate Kam Chancellor going for an interception.
