Paxton Lynch isn't the only Denver Broncos quarterback on the mend.

Per Mike Klis of 9News, rookie signal-caller Chad Kelly has begun throwing and is eligible to resume practicing Monday, joining linebacker Shane Ray and tight end Jake Butt.

Kelly has not been told he will practice, however, according to Klis.

The team's seventh-round pick -- the Mr. Irrelevant of this year's Draft -- Kelly has been shelved on the Non-Football Injury list as he recovers from April surgery to repair a ruptured ligament in his throwing wrist. He was fully expected to be given a "redshirt" year by the Broncos, who have no need to rush the Ole Miss product.

But Kelly is ramping up his work, and will be throwing up to 35 yards by the end of the week.

“I’m feeling really good,’’ he said.

The Broncos would have 21 days to activate him from the day he returns to practice, per NFL rules. It's highly unlikely he's promoted to the active roster at any point in 2017.

Lynch, meanwhile, took part in his own throwing session Wednesday, tossing 15 balls after practice -- his first on-field drills since spraining his right shoulder in August. He remains without a timeline to practice in full.

“I don’t know,’’ he told Klis. “I just know it’s OK to start throwing and the doctor said we’ll progress from there.’’

Broncos coach Vance Joseph has said Lynch won't see action until he's 100-percent healthy. It's possible, if not probable, he's eventually placed on injured reserve, ending his season and freeing a roster spot for Ray or Butt.

Brock Osweiler is entrenched as the backup to starting QB Trevor Siemian.
