The Colts didn't even wait for the free-agent market to open before making their first signing.

On Thursday, they signed former Browns linebacker D'Qwell Jackson. Terms of the deal were not immediately available.

A second-round draft pick in 2006, the 6-foot, 240-pound linebacker has started 48 consecutive games and has 891 career tackles, 11½ sacks, eight interceptions and seven fumble recoveries. Last year, he led the Browns with 143 tackles, had 1½ sacks, one interception and one fumble recovery.

In Indianapolis, he will be reunited with former coach Rod Chudzinksi and running back Trent Richardson, both of whom began last season in Cleveland.
