Both are in the XV for the Celtic Cup quarter-final against Munster, the Celtic League champions.
Dan has played in Glasgow's two previous matches as a replacement. David had his first Celtic appearance against Connacht last Friday, also as a substitute, after he had been unavailable for the start of the season because of an ankle injury.
Rory Kerr and Matt Proudfoot, return to the starting line-up after injuries. Rory took a shoulder knock in the game against Ulster three weeks ago, and Matt has been absent for the same time because a knee injury.
Glasgow have made eight changes, one positional, from the team who started in the league match that Glasgow lost to Connacht by 19-30 at Hughenden last Friday. Four players from that team are unavailable this week because of injuries – Jon Steel, Graeme Morrison, Mark McMillan, and Andrew Kelly.
Rory Kerr and David Millard come in on the wings. Gareth Maclure switches to outside centre and Dan Parks and Kenny Sinclair replace Calvin Howarth and Mark McMillan as half-backs whereas Matt Proudfoot, Nathan Ross, and Paul Dearlove resume in the pack in place of Andy Kelly, Joe Beardshaw, and Roland Reid.
Because of injuries to scrum halves, Mark McMillan and Sam "The Claw" Pinder, as well as Graeme Beveridge's absence on World Cup duty, Glasgow have again called up Richard McKnight from Glasgow Hawks for duty among the replacements. Richie was also called up in the previous round of the cup competition, when Glasgow beat Celtic Warriors by 19-9 at Bridgend two weeks ago.

Glasgow's Sean Lamont and Lee Harrison fielded questions from supporters at a meeting at Hughenden last night. It was interesting to get a player's perspective on a number of issues. Thanks to Sean and Lee, and to Gordon Hood of Glasgow Warriors for an interesting and enjoyable evening.
