ST. LOUIS (AP) -- Defensive end Shea McClellin is back in the lineup for the Chicago Bears after missing two games with a hamstring injury.
But against St. Louis on Sunday, Chicago's line is missing tackle Stephen Paea, who is inactive with a toe injury.
Rams rookie safety T.J. McDonald was activated from injured reserve-designated for return Saturday and could start. He started the first four games of the season before breaking a bone in his right leg.
Right guard Harvey Dahl (knee) missed a third start for the St. Louis Rams, and tackle Rodger Saffold was expected to start for the second straight game.
Bears cornerback Isaiah Frey (hand) is active.
