"There's a chance," Padres manager Bud Black said. "That's his motivation to come back and pitch. The doctors say we have to let the pain subside and let the healing start to occur."
Marquis suffered a fractured trapezium bone in his left hand on Tuesday after taking a line drive off his glove hand in the second inning against the Pirates. He was placed on the disabled list Thursday.
"Only time will tell. We will see," Marquis said. "As time goes and the healing process takes it course, we will see where it's at."
Marquis, who is wearing a cast, said he will continue to throw bullpens and hopes the swelling around the broken bone goes down during the next two weeks. The right-hander said he knew the hand was broken but continued to pitch.
"I love the game. I love being out on the mound and I love competing," he said. "It hurt but if you want to be on the mound, you have to deal with it sometimes."
Marquis is 8-11 with a 5.22 ERA in 22 starts this season. He's 5-3 with a 4.55 ERA in his last 10 games.
"If I'm able to pitch, I will. If it makes no sense, I won't," he said. "But my goal is to get on the mound as many times as I could."
For their part, the Padres believed placing Marquis on the disabled list was the right decision.
"If this was a situation, maybe late in the year, or a different type of season, then there might be a possibility that he could continue pitching," Black said. "It makes sense to let it heal in the short term. He's in a lot of pain. He's got a cast up to his elbow. Jason understands that."
