The San Diego Chargers placed wide receiver Seyi Ajirotutu and center David Molk on injured reserve and replaced them Tuesday with center Colin Baxter and guard-tackle Stephen Schilling.
Ajirotutu (hand) and Molk (thumb) were hurt Sunday in a 20-13 loss to the Cincinnati Bengals.
Baxter played in five games with the Chargers in 2011. He was released by the Chargers at the end of training camp this year.
Schilling was a sixth-round draft pick by the Bolts in 2011. He played in nine games and started one game each at right and left guard as a rookie. He also was released at the end of camp.
