The Spain international had been booked earlier in the match, and both he and Barry received a yellow card after the confrontation late in the contest. Per Rob Harris of the Associated Press, we may not have heard the last of the incident:

Chelsea released a statement after the match about the incident:
Diego spoke to club officials after the game and expressed regret over his reaction to the challenge from Gareth Barry that led to his red card, but Diego was also very clear that he did not bite him at any point during that altercation.
On Sunday, Sky Sports News HQ revealed that Barry confirmed Costa did not bite him.
Bleacher Report's Garry Hayes shared his thoughts:
Watching the Costa sending off again - he can only blame himself. Got some silly criticism earlier in the game, but that's just ridiculous.— Garry Hayes (@garryhayes) March 12, 2016
Everton won the match, 2-0. Per Harris, it was Costa's first red card as a member of the Blues.
Barry ended up taking an early shower as well, as he lashed out at Cesc Fabregas minutes after Costa was sent off.
Unsurprisingly, the incident caused quite an uproar on social media. Per Paul Hayward of the Daily Telegraph, it was only the latest in a long line of clashes involving the Spaniard:

ESPN FC's Tommy Smyth wasn't sure whether Costa bit his opponent or changed his mind just in time:
Did Costa think he was Suarez was he going to bite. What the heck is wrong with these guys ?— Tommy Smyth (@TommySmythESPN) March 12, 2016
Barry didn't exaggerate the incident or reach for his neck, which only fueled discussion about what the Spaniard actually did.
Although Barry stated Costa didn't bite him, the encounter is sure to remind fans of Barcelona forward Luis Suarez, who was caught biting opponents on the pitch on three separate occasions.
Sport Witness noted Costa's punishment won't be as harsh as what was handed to Suarez, who was banned for four months and nine international matches:
Of course Costa won't get a similar ban to Suarez because it's not the third time he's tried to have dinner on the pitch.— Sport Witness (@Sport_Witness) March 12, 2016
Still, the Football Association will likely take a long, hard look at video of the confrontation to try to determine Costa's intent and whether or not he bit Barry.
Per Metro's Tom Olver, there were also questions about whether Costa intended to spit at the referee's feet earlier in the match, so regardless of the FA's decision regarding the altercation, it's possible he could miss a healthy chunk of playing time.
