Lions' Bush on track to return

Detroit Lions running back Reggie Bush put in a second consecutive full practice on Thursday, increasing his likelihood of playing in Sunday's game against NFC North rival Chicago.

Bush was inactive for the Lions' 27-20 Week 3 victory at Washington due to a bruised left knee the versatile veteran sustained in a loss at Arizona the previous Sunday.

The eighth-year pro, who signed with Detroit as a free agent during the offseason, totaled 191 yards from scrimmage and had a 77-yard touchdown catch in his Lions' debut in Week 1, a 34-24 home win over Minnesota.

Bush will likely share time with Joique Bell, who put up 132 yards from scrimmage with a touchdown against the Redskins, if he's active on Sunday.

Three other Lions, most notably star wide receiver Calvin Johnson (knee), were limited participants in Thursday's practice after sitting out Wednesday's session. Safety Louis Delmas (knee) and left guard Rob Sims (shoulder) also got in some work.

The only Detroit player absent from Thursday's workout was wide receiver Nate Burleson, who is expected to miss between 6-to-8 weeks after fracturing his arm in a car accident earlier in the week.
