Ebron, who made the Pro Bowl in 2018 after having 13 touchdown receptions, had three of the Colts' six dropped balls against the Raiders.
"I didn't do anything. I didn't contribute. I didn't help my teammates. I was s---ty," Ebron said. "It sucked to be a part of, and hopefully next week I'll do something more. ...
"It's definitely lack of concentration. It's just mental. Just going through a drought. First time ever going through something like this where I had three drops in one game. It's tough."
All three of Ebron's drops occurred in the first half, when the Colts were trying to come back from two 14-point deficits. Two of the drops would have given the Colts a first down, and the third happened one play prior to rookie receiver Parris Campbell's fumbling at Oakland's 15-yard line with less than four minutes remaining in the first half.
Ebron threw his helmet down on the sideline twice -- first after he was taken out the game and then again after the Campbell fumble.
"I really pride myself being a very, very prideful person," Ebron said. "When these mistakes happen, they hurt because it's not something I want to do, something I try to do. They just happen. But being a professional, I have to learn how to let it go and help my team. [Sunday,] I didn't do that. That sucked."
Ebron's lone reception on five targets was a 48-yard touchdown reception late in the game. He didn't celebrate like he usually does. He simply returned to the sideline after the touchdown.
"I didn't even deserve that [touchdown], not after my performance," said Ebron, who had six drops in all of 2018. "I just have to be better for my teammates. I was a bit disgusted from that performance."
