IndyCar, after just two races, is suddenly rife with rumors about driver free agency. The Arrow McLaren driver dislocated his wrist and tore tendons in a mountain biking crash a month before the season opener. When the 22-year-old Malukas misses Sunday’s race at Barber Motorsports Park in Alabam, he will have been out of the car for six outings that includes an exhibition race and an Indianapolis 500 test.
