Wes Welker, a wide receiver for the Denver Broncos, has reportedly been suspended for four games after testing positive for amphetamine in May.
Citing anonymous sources, NFL.com reporter Albert Breer said via Twitter on Tuesday that Welker tested positive for the banned performance-enhancing drug and would be sitting out the start of the season.
Welker failed the test in May, NFL.com reports, so the suspension should not be a shock to Broncos leadership, which had prepared for a shakeup. Welker has also been dealing with injuries this year: two weeks ago, he suffered his third concussion in the past 10 months.
The Broncos open the NFL season Sunday with a matchup against the Indianapolis Colts.
