Bucs' Seferian-Jenkins excused from practice for 'not knowing what he was doing'

Tampa Bay Buccaneers tight end Austin Seferian-Jenkins gave fans a bit of a scare after walking off the field during practice Thursday.

Following his departure, Seferian-Jenkins sent a tweet from the Bucs' locker room, that's since been deleted, with the phrase "MOVING ON".

Given the unknown reason for his departure and the cryptic Tweet, thoughts of a potential trade swirled, but head coach Dirk Koetter offered a much simpler explanation, once practice was over.

Koetter told reporters that Seferian-Jenkins was sent off the field because "he didn't know what he was doing," according to Rick Stroud of the Tampa Bay Times. Koetter refused to elaborate, stating the details were "between us".

Seferian-Jenkins wowed the league with a five-catch, 110-yard performance in Week 1 of the 2015 NFL season, but failed to crack the 60-yard mark in the six other games he played last year.

The 23-year-old is in his third season with the Bucs, and has apparently already moved on from Thursday's practice.
