Philadelphia Eagles coach Chip Kelly has heaped praise on new quarterback Tim Tebow for his form in training camp.

Tebow joined the Eagles on a one-year contract after a two-season break, although he is not expected to feature too heavily at the beginning of the season.

However, Kelly told the Delaware County Times: "I have seen an improvement from Tim since the day we got him in terms of his knowledge of what we're doing, understanding where everybody is. There's a whole process, and for him what we have done is different than what he's done anywhere else.

"So in terms of learning our terminology and how we do things, I think each week you've seen an incremental bump in him, so we're excited to see where that takes him and it'll be a good competition as we get into August."

Tebow spent two seasons with the Denver Broncos, a year with the New York Jets and a year with the New England Patriots, who released him in 2013.
