FOXBOROUGH, Mass. -- New England Patriots tight end Lance Kendricks has been suspended one game for violating the NFL's policy on substances of abuse, the league announced Saturday.

Kendricks, 31, has been on the roster bubble as the Patriots have had an open competition among several players as they attempt to fill the void created by Rob Gronkowski's retirement.

The Patriots had signed Kendricks to a one-year deal on July 24. He spent the previous two seasons with the Green Bay Packers.

Kendricks is eligible to participate in all remaining preseason practices and the team's final preseason game Thursday against the New York Giants. He will be eligible to return to the Patriots' active roster on Sept. 9, following the team's Week 1 game versus Pittsburgh.

Kendricks played 24 snaps and had one catch for 11 yards in the Patriots' win over the Carolina Panthers on Thursday.

In a Week 2 preseason win over the Tennessee Titans, Kendricks also played 24 snaps and had one catch for 28 yards. He had been penalized for holding in the end zone in that game, resulting in a safety.

Veteran tight end Benjamin Watson, who also is vying for a roster spot, is suspended for the first four games of the season for violating the league's policy on performance-enhancing drugs.
