KANSAS CITY, Mo. (AP) -The Kansas City Chiefs have released offensive guard John Welbourn in what figures to be the beginning of a postseason roster shakeup.

The Chiefs lost their last nine games of 2007, finishing 4-12 in their worst season in 30 years.

The 31-year-old Welbourn, who was released Thursday, started every game last season at right guard. Right tackle Chris Terry, a part-time starter, was let go late in the year.

The Chiefs might also choose to not re-sign starting center Casey Wiegmann. Kyle Turley, a part-time starter at both guard and tackle, announced at the end of the season he was retiring.

Also released were two backups who saw almost no playing time last year, running back Gilbert Harris and defensive end Khreem Smith.

Other players who might be released include cornerback Ty Law, tight end Jason Dunn, wide receiver Samie Parker and linebacker Kendrell Bell.
