San Diego Chargers linebacker Jyles Tucker has been placed on injured reserve, reports Kevin Acee of the San Diego Union-Tribune.

Tucker (6-3, 258) missed Week 3 for personal reasons, but returned to action on Sunday, posting his first quarterback sack of the season during the third quarter of the Chargers' 41-7 drubbing of the Arizona Cardinals.

Unfortunately, Tucker tore a pectoral muscle and will land on injured reserve for the second consecutive season. Tucker was placed on IR last November with an ankle injury.

The undrafted free agent from Wake Forest has 56 tackles, including 10 quarterback sacks during his 29-game career.
