Just when it looked like Washington Redskins tight end Jordan Reed was ready to have a healthy season, he left his team's third preseason game with a head injury on Thursday night, and now, more bad news has come out.

According to Ian Rapoport of NFL Network, Reed has been placed in the NFL's concussion protocol. This is at least the fourth concussion of Reed's playing career.

Reed, who played his collegiate football at the University of Florida, was originally selected by the Redskins in the third round (85th pick overall) of the 2013 NFL Draft.

The 29-year-old has never played a full season due to a myriad of injuries.

He appeared in just nine contests during his rookie year, catching 45 passes for 499 yards and three touchdowns. Reed then followed that up by participating in 11 games in his second season, registering 50 catches for 465 yards.

The New London, Ct. native had a breakout year in 2015, hauling in 87 receptions for 952 yards and 11 scores. Not so coincidentally, that season also marked Reed's most active campaign in terms of games played, as he took part in 14 contests.

Reed then made his first Pro Bowl in 2016, snaring 66 balls for 686 yards while reaching the end zone six times. However, he was limited to just 12 games due to a concussion and a shoulder injury.

He went on to play in just six games in 2017 before having a fairly healthy season in 2018, making 13 appearances and finishing with 54 receptions for 558 yards and a couple of touchdowns.

The Redskins will play their final preseason game next Thursday against the Baltimore Ravens.
