SANTA CLARA, Calif. (AP) - Alex Smith is supportive of Colin Kaepernick's success, even if the second-year pro takes Smith's starting job as 49ers quarterback.
Smith plans to fight for his job once he is fully healthy - and he had yet to be medically cleared Wednesday. Yet coach Jim Harbaugh said that once Smith is available, the starting QB for the NFC West-leading Niners (7-2-1) could change week to week, and even during the course of a game. Harbaugh gave no indication when he would select his No. 1 for Sunday's game at New Orleans (5-5).
Harbaugh underwent a follow-up for his irregular heartbeat Tuesday and said ``believe we've got that one licked.'' He has quit chewing tobacco and given up the four or five Diet Cokes he was drinking daily.
