Redskins offensive lineman Mike Williams is expected to miss the entire 2010 season after blood clots were discovered near his heart, The Washington Post reported Saturday.
According to the report, Williams was recently hospitalized for the problem and the Redskins are concerned the issue could threaten his career.
Williams was expected to compete for the starting right guard position after starting eight games for Washington last year.
Williams moved to the interior of the offensive line upon joining the Redskins last offseason. Williams had been out of football for two years and last played in the 2005 season for the Buffalo Bills -- the team that drafted him fourth overall out of the University of Texas in 2002.
Williams, an All-American tackle for the Longhorns, struggled at right tackle for the Bills, but seemed to fit in well in his first season at guard. The Redskins re-signed him earlier this offseason.
