Colin Kaepernick*49ers quarterback Colin Kaepernick fired back at Twitter critic who blasted him, and he didn’t let up — putting the user in his place, according to NY Daily News.

“1000 abs…. arm workout….. 10 min straight on the jump rope…. 2 hour study session in February….. that’s what we call a recovery day!” Kaepernick tweeted.

“Ab workout won’t help find open receiver #study,” Twitter user @battman_returns wrote, mocking the quarterback. Maybe, that wasn’t the best idea being that Kaepernick was up for the fight.

“Are you illiterate or just ignorant? Read the tweet again better yet give me your breakdown of every defensive coverage,” Kaepernick replied.

“I want every players responsibility on every coverage if you can’t do it mind your damn business clown!” @battman_returns added.

But Kaepernick was ready for the Twitter war. And his last tweet was the most epic of them all — completely shutting down the critic.

“You got 8 followers bruh your own family don’t even want to know what you doin! Get better at life!”
