Channel 4’s Don Postles may stay put on “The 10 O’Clock News” on WNLO-TV.

Likewise for Diana Fairbanks on Channel 4’s “Wake Up.”

That’s the word from Channel 4 General Manager Chris Musial.

In a telephone interview, Musial said the station is actively looking for a new anchor to replace Fairbanks on the 5:30 and 10 p.m. newscast since she left to work mornings. But he added the new hire won’t necessarily fill Fairbanks’ 10 p.m. anchor slot.

“Don is doing a great job on the 10 and [news director Joe Schlaerth] may choose to use the person hired across different time periods,” said Musial.

He wouldn’t say whether Fairbanks’ supposed tryout move to mornings is now permanent but it appears to be. “We’re really happy with the pairing of Diana and [new anchor] Jordan Williams,” said Musial. “We have some growth in the morning.”

Musial stopped short of saying the new roles for Postles and Fairbanks will be permanent.

“It is staying put for now the way it is,” said Musial.

In a week, Channel 4’s dominant 10 O’Clock News may face a stiffer challenge when Channel 2’s newscast at that time goes from little-watched WNYO to Fox affiliate WUTV. Musial doesn’t seem all that worried.

“It is a natural thing for them to do,” said Musial. “However, we have built a very loyal following and the November and February ratings books showed we continue to grow that audience. In 2000 or 2001, we identified a need that people wanted to watch news earlier and get up earlier. I always say I love the competition, and I think we’ll be fine. We do a real solid job at 10 and 11. I think we’re going to be fine.”
