Seattle Seahawks tight end Elijah Arroyo (knee) missed a second consecutive practice on Thursday. The rookie is trending in the wrong direction ahead of Week 15 against the Indianapolis Colts, and he'd likely need to get on the field in some capacity on Friday to have any shot at playing on Sunday afternoon. The Seahawks invested a second-round pick in Arroyo this year, but he has consistently operated in the No. 2 tight end role behind A.J. Barner. He has just 15 catches, 179 yards, and one touchdown in his rookie campaign, ranking as the overall TE53 in PPR leagues. Assuming Arroyo doesn't play this week, the Seahawks could activate Eric Saubert (calf) from injured reserve to back up Barner against the Colts.

Las Vegas Raiders wide receiver Dont'e Thornton Jr. (concussion) upgraded to a full participant in practice on Thursday. He had previously opened the week in a limited capacity. It appears that Thornton is trending in the right direction to clear concussion protocol and play in Sunday's Week 15 contest against the Philadelphia Eagles. The 23-year-old has been underwhelming in his first NFL season, even after teammate Jakobi Meyers was traded away. He ranks as the overall WR138 in PPR leagues with 25 targets, eight catches, and 123 yards so far this year. Even if he's confirmed as active on Sunday, Thornton can be avoided in all fantasy leagues.

Las Vegas Raiders tight end Michael Mayer (ankle) was a full participant in practice on Thursday. This was an upgrade for the backup tight end after he logged a limited practice session on Wednesday. Mayer is working his way back from a two-game absence, and it looks like he should suit up against the Philadelphia Eagles in Week 15, barring any sort of setback. The 24-year-old is one of the better backup tight ends in the NFL, but he still doesn't handle enough volume in his role behind Brock Bowers to justify starting him in fantasy football. To make matters worse, Mayer will likely be catching passes from Kenny Pickett this week with Geno Smith (shoulder, back) not expected to play.

Pittsburgh Steelers tight end Darnell Washington (concussion) was a limited participant in practice on Thursday, and he remains in concussion protocol ahead of Sunday's Week 15 contest against the Miami Dolphins. Washington exited last week's game early after catching just one pass for 12 yards. He had looked solid in his nine previous contests, though, totaling 22 catches, 276 yards, and one touchdown during that span. The 24-year-old has quietly passed Jonnu Smith and Pat Freiermuth in terms of snap count, but his fantasy production has still left a lot to be desired. He can be dropped in redraft leagues and stashed in deeper dynasty formats.
