After missing shows over the last week, including on Monday, his co-host Bryan Hayes on 'Overdrive', a program on TSN1050 Radio, commented on the matter, saying that O'Neill is doing okay.
O'Neill joined TSN in 2013, six years after announcing his retirement from the National Hockey League. He's been seen on intermission panels during Maple Leafs and World Junior games on TSN, as well as on the radio with 'Overdrive', as mentioned above.
The King City (Ontario) native was a fifth overall pick of Hartford back in 1994 and went on to appear in 11 NHL seasons with the Whalers, Hurricanes and Maple Leafs. He played a crucial role in the 2002 Stanley Cup Playoffs helping the Hurricanes reach the Final for the first time in franchise history.
