The Ravens (6-2) play at the Cincinnati Bengals (0-8) on Sunday and will aim to extend their winning streak to four games. The coach didn't want to speculate on the receiver's status for this weekend.
Green has not played since he tore multiple ligaments in his left ankle during the Bengals' first practice of the preseason.
For now, Green said he's going to take things "day-by-day". "I just take it day-by-day".
"He could be considered the best receiver in football, certainly right there with all of them", Harbaugh said Wednesday during a teleconference.
"I can't go out there when I'm not 100 percent", Green told reporters Thursday, per Jay Morrison of The Athletic.
Therefore, Green missed practice and is back on the mend once again. "Now I'm just getting it out of my mind and understanding that it's fine".
"I think he's been making great progress", Taylor said.
Green missed several weeks last season with a foot injury, which he promptly reinjured in his first game back. "I'm not really anxious about that situation".
Green is also in the final year of his four-year, $60 million contract with the Bengals and is looking for a long-term deal. The Bengals were hopeful that Green would be able to return from his ankle injury this week, but those plans went out the window on Wednesday when the receiver's ankle started to swell up on him.
Green, the fourth-overall pick in the 2011 NFL Draft, has averaged 75 receptions and 1,113 yards per season during his eight-year career.
