Stefon Diggs quickly left Highmark Stadium after Bills' loss to Bengals

There may be some unrest brewing in Orchard Park. 

Following the Buffalo Bills' 27-10 loss against the Cincinnati Bengals Sunday in the AFC divisional round playoff, wideout Stefon Diggs left Highmark Stadium in haste, per Joe Buscaglia of The Athletic. 

Diggs "darted" out of the Bills' locker room shortly after the game before being coerced back by running back Duke Johnson. According to Buscaglia, Diggs left again "a few minutes later." 

Jon Scott of Spectrum News confirmed that Diggs left the locker room before media availability, adding that he wasn't the only Bills player to exit early. 

Diggs appeared frustrated throughout the game after several failed connections with quarterback Josh Allen. 

Late in the fourth quarter, a visibly upset Diggs gestured emphatically in Allen's direction while standing on the sidelines. Allen, sitting on the bench, paid Diggs no mind.

 Sunday marked the second-straight lackluster performance for Diggs in the divisional round. 

Last season, against the Kansas City Chiefs, Diggs caught three passes for seven yards while being targeted only six times in a 42-36 loss. 

Whatever the issue between Diggs and Allen, it's something the Bills will have to fix quickly. 

Both Diggs and Allen are locked up long-term. Diggs is under contract through the 2027 season. Meanwhile, Allen signed a six-year, $258M extension in 2021, which begins in 2023.
