The right-hander gave up three hits, struck out 11, threw his second straight complete game and continued his dominance since returning from the disabled list on June 1.
In a two-strike hole, Jackson barely nicked a pitch before fouling off two more and dropping his game-tying RBI single into right-center, the flair just eluding a diving Blackmon.
Brantley, who played in just 11 games last season following right shoulder surgery, started running after a fly to center when he pulled up.
Brantley, who was on the disabled list in June with a sprain to the same ankle, limped slowly off the field to an ovation and was helped down the dugout steps.
Indians: Francona said All-Star LHP Andrew Miller may need a few days beyond his stint on the 10-day disabled list to recover from right knee tendinitis.
