AUTO RACING

Dale Earnhardt Jr. will join NBC Sports Group’s coverage of stock car racing next year.

The agreement with NBCUniversal will allow Earnhardt to pursue “a wide range of opportunities in the company’s media businesses, including movies, television, podcasts, and other areas.”

Earnhardt announced in April he would retire after this season, in part because of his injury history. Two big crashes last summer forced him out of the final 18 races, and he missed two races during the 2012 playoffs also because of concussion-related symptoms.

The 42-year-old Earnhardt intends to compete in two Xfinity Series races next season and plans to be involved in the sport in other ways, when his broadcasting duties allow it.

NHL

Buffalo Sabres winger Kyle Okposo said he is fully healthy after a concussion led to sleeping trouble, significant weight loss and a trip to intensive care last March.

Okposo missed the final few weeks of Buffalo’s season with a previously undisclosed illness. In a letter posted on the team’s website Monday, Okposo said a routine hit in practice caused his mood to change and other problems that required hospitalization.

The 29-year-old said he lost his appetite, had a negative reaction to sleep medications and that at one point he weighed less than 200 pounds. He spent time in the Neuro Surgical ICU at Buffalo General Hospital to be stabilized. Okposo’s playing weight is listed at 218 pounds.

• The Nashville Predators have signed forward Austin Watson to a three-year $3.3 million deal keeping him under contract through 2019-20.
