“Nathan McAndrew has come for T20 and those two four-dayers which gives us back-up for the bowlers, then Farooqi gives us options with Colin still here as well.
“The T20 fixture list is pretty tough [with back-to-back fixtures] so it’s touch and go whether fast bowlers can play every game.
“It’s not just for that tournament, it’s the impact it has down the line later in the season, so we’re trying to look after the bowling unit and how we manage that group.”
New South Wales paceman Ryan Hadley will be in action alongside Ingram for the opening six Championship matches in April and May.
Glamorgan announced his signing after Dawson saw him in action for Australia A against England Lions in Brisbane in December.
“He hit the deck hard and bowled a good pace, I watched a lot of his footage for New South Wales this year and he got highly recommended, so he’s keen to come and make an impact for Glamorgan,” Dawson said.
Glamorgan’s first Championship fixture back in Division One is at home to Yorkshire starting on Friday, 3 April.
