Rookie defensive end/long snapper Jake Laptad was re-signed Tuesday to replace 14-year veteran long snapper Patrick Mannelly, who was placed on injured reserve Monday with a ruptured ACL in his left knee.
Laptad spent training camp and the preseason with the Bears after signing as an undrafted free agent out of Kansas. He handled all the long-snapping in the preseason finale without incident but was waived Sept. 2.
The Bears' active roster stands at 52 players, with the final spot expected to be filled this week by a veteran quarterback to back up Caleb Hanie.
Also Tuesday, offensive tackle Josh Davis and cornerback Joshua Moore were signed to the practice squad.
Moore was the Bears' fifth-round selection (141st overall) in the 2010 draft. He played in three games last season and had 1 special-teams tackle.
The 6-foot-6, 310-pound Davis spent the preseason with the Bears after signing as an undrafted free agent out of Georgia.
