Thompson, who has played through an undisclosed illness the past two games, was not seen at shootaround late Tuesday morning. With the two-time NBA All-Star sidelined, head coach Steve Kerr is expected to start rookie Patrick McCaw in Thompson's place. A second-round pick from UNLV, McCaw's playing time has fallen off significantly in recent weeks as Ian Clark has beaten him out for the backup shooting guard spot. On Dec. 5, when Thompson scored a career-high 60 points in 29 minutes, he needed only 88.4 seconds of possession, 52 touches, 33 shots and 11 dribbles. After facing the Heat, which owns the league's second-worst record at 11-28, Golden State hosts Detroit on Thursday.
