​Call it the tyranny of the short week.

One day after notching a 34-7 home win over Arizona, Philadelphia Eagles head coach Doug Pederson told reporters Monday that starting right tackle Lane Johnson is going through the NFL's concussion protocol.

​​While that may not be concern during a regular week, as he could be cleared on Thursday or Friday and play, like Packers WR Davante ​​Adams was this past week, it's much harder to get cleared on a short week. 

That said, Johnson was hopeful to play when he spoke with reporters on Sunday. 

Johnson left Sunday's game with what was initially reported as a head injury and did not return. 

The 4-1 Eagles have been flying of late, and the play of the offensive line has played an essential role in their success. Assuming Johnson is unable to go for Week 6, Halapoulivaati Vaitai is in line to start at right tackle.

Quarterback Carson Wentz likely won't be happy about trotting out without the fifth-year veteran, however.
