HOUSTON (AP) -The Houston Texans re-signed Will Demps and N.D. Kalu on Thursday.

Demps appeared in 15 games with eight starts at safety in his first season with the Texans in 2007. He finished with 49 tackles, two forced fumbles and a fumble recovery. He also made three tackles and recovered a fumble on special teams.

Demps averaged 6.5 tackles over the last seven games in 2007. He made a season-high 12 tackles at Tennessee on Dec. 2 and he forced and recovered a fumble the following week against Tampa Bay.

The 6-foot-3, 257-pound Kalu played in 15 games last season, recording 13 tackles, including three sacks. His sack total was his highest since 2003, when he recorded 5.5 for Philadelphia. In two years with Houston, Kalu has played in 30 games with four starts and made 34 tackles, including five sacks.
