Clay did not participate in Sunday's practice due to an undisclosed reason, Mike Rodak of ESPN.com reports.

EDGE Analysis

The reason for Clay's absence is unclear at this point, but the Bills' No. 1 tight end was also a non-factor during Friday's preseason win over the Browns. Clay may not be dealing with a significant injury, but backup Nick O'Leary produced four receptions for 70 yards and a touchdown in place of Clay on Friday.

Clay is the leader of a Buffalo tight end group that didn't add any new players during the offseason, Jay Skurski of The Buffalo New reports.

EDGE Analysis

Clay has been oddly consistent through three seasons of a five-year, $38 million contract, landing in the range of 13-15 games, 49-57 catches, 528-558 yards, 74-87 targets and 2-4 touchdowns each year. He was slightly more productive his final two seasons in Miami, but it was essentially the same idea with a bit more target volume. While the 29-year-old could push for six or seven looks per game in a Buffalo offense devoid of other options, it won't come as any surprise if his efficiency suffers while the team works in new players at quarterback and along the offensive line. There's also some chance backup TE Nick O'Leary takes on a slightly larger pass-catching role, after hauling in 22 of 32 targets for 322 yards and two touchdowns last year.

Clay brought in three of five targets for 15 yards in Sunday's 10-3 AFC wild-card loss to the Jaguars.

EDGE Analysis

Clay was able to overcome an in-game hamstring injury and finish out the contest. His catch total was a team high, but his middling 5.0 YPC spoke to the minimal impact he had overall. The modest numbers represent an underwhelming finish to a strong season for Clay, one that saw him bring in 49 of 74 targets for 558 yards and two touchdowns while fumbling once over 13 games.

Clay returned Sunday's playoff game against the Jaguars after previously exiting with a hamstring injury.

EDGE Analysis

The Bills offense Sunday has largely been driven by running back LeSean McCoy, who is toughing things out through an ankle injury. The return of Clay, however, does at least give QB Tyrod Taylor another familiar option in the passing game.

Clay was forced out of Sunday's playoff game against the Jaguars with a hamstring injury.

EDGE Analysis

Clay has been managing a knee issue of late, with the hamstring injury representing a new issue for the tight end. Prior to his exit from Sunday's contest, Clay caught his only target for no gain.

Clay (knee) does not carry an injury designation for Sunday's playoff game against the Jaguars.

EDGE Analysis

Clay's practice limitations this week were nothing out of the ordinary and maintenance-related, so his removal from the Bills' final injury report in advance of wild-card weekend was fairly routine. With running back LeSean McCoy (ankle) banged up, Clay figures to be a focal point in the Bills attack Sunday, though it's hardly a cake matchup for the tight end against the rugged Jaguars passing defense.

Clay (knee) was a limited participant in Wednesday's practice.

EDGE Analysis

Clay was able to play through the nagging knee injury in the Bills' regular season finale, posting six catches for 64 yards on eight targets against the Dolphins. The Bills' No. 1 tight end figures to be ready for the team's wild-card matchup against the Jaguars on Sunday.

Clay brought in six of eight targets for 64 yards in Sunday's 22-16 win over the Dolphins.

EDGE Analysis

The veteran tight end paced the Bills in receptions and receiving yards, generating a productive effort against many of his former Dolphins teammates for the second time in the last three games. Clay posted 11 receptions for 132 yards in his two games versus Miami, generating his second- and third-highest single-game yardage totals of the campaign in the process. Given that the Bills will face a pair of lockdown corners in next Sunday's AFC road wild-card contest against the Jaguars, Clay could play a sizable role in the game plan, especially if LeSean McCoy (ankle) is also limited or sidelined.

Clay (knee) doesn't have a designation for Sunday's contest in Miami.

EDGE Analysis

Since sitting out three games midseason due to a knee injury, Clay's practice reps have been monitored weekly with game day in mind. Consequently, he's been able to handle at least 60 percent of the offensive snaps in six of the last seven contests. Tyrod Taylor has looked Clay's way 19 times over the last two games, including a Week 15 matchup against the Dolphins in which the tight end hauled in five of nine passes for 68 yards.

Clay (knee) will be limited during Wednesday's opening practice of the week, Mike Rodak of ESPN.com reports.

EDGE Analysis

Clay's knee is an ongoing issue and the team monitoring his reps throughout the week has become the standard. He'll play this weekend against the Dolphins in a must-win game for the Bills and their playoff chances.
