Indianapolis signs offensive lineman to help fill gaps left by injured players

The Indianapolis Colts have signed offensive lineman James Williams, an undrafted rookie from Harvard.

To make room on the roster, the Colts released offensive lineman Andy Alleman, an offseason veteran free agent acquisition. Alleman has not practiced since hurting his back Friday.

Left tackle Charlie Johnson has not practiced since spraining his right foot Friday afternoon.

Four-time Pro Bowl center Jeff Saturday and rookie guard Jacques McClendon also missed their second straight morning workouts Tuesday. Also missing was right tackle Ryan Diem, whose wife gave birth to the couple's first child last week.
