Bethel-Thompson added to practice squad

SANTA CLARA, Calif. -- The San Francisco 49ers will be a three-quarterback team again.

The 49ers are adding quarterback McLeod Bethel-Thompson to the practice squad. He was cut by the 49ers on Tuesday to make room for star receiver Michael Crabtree on the 53-man roster. Bethel-Thompson cleared waivers Wednesday.

The 49ers will have just Colin Kaepernick and Colt McCoy on the active roster, but Bethel-Thompson will continue to practice and be able to be moved up to the active roster if there is an injury. The 49ers claimed Bethel-Thompson, a San Francisco native, off waivers from Minnesota earlier this season. He was with the 49ers in camp two years ago.

In other 49ers notes:

San Francisco coach Jim Harbaugh said Wednesday it is feasible that CB Tramaine Brock stays in the starting lineup even when Tarell Brown (ribs) returns. Brown will likely be back in a week or so. Brock was promoted from the No. 3 cornerback when Brown was injured. Brown signed a four-year contract extension last week. It is a clear sign the team thinks he is a starter of the future.

Justin Smith was awarded an extra sack for his efforts against Washington. He finished with two in the game. Smith, Aldon Smith and Ahmad Brooks each had two sacks in the game.

Brooks, who is having a tremendous season, discusses a variety topics in this ESPN Radio interview.
