Knight (ankle) is considered doubtful to play Friday against the Hawks, the Suns' official site reports. Knight sustained a left ankle sprain during Monday's game, which will relegate him to a spectator Wednesday. He's wearing a brace on the ankle as well as a walking boot for additional protection, and during Tuesday's practice, he was seen on crutches. As a result, an appearance Friday appears slim. In his stead, Marcus Morris will be afforded his 20th start of the season Wednesday.
