Having captured second spot last week after their thrashing against Courts Young Lions, the Jaguars were looking to keep it against bottom 3 Geylang International but nobody told the Eagles the script as the Bedok side beat Tanjong Pagar 2-1 in Bedok.
The Jaguars took the lead through Kamel Ramdani but the Eagles came back through Norihiro Kawakami and skipper Jozef Kaplan before half-time.
In the second half, the Jaguars was as bad as they never knocked on the door and the home side should have increased the lead further.
Albirex Niigata (S) took full advantage as they defeated Balestier Khalsa 1-0 at Toa Poyah.
Shingo Suzuki got the goal 10 minutes before the end as the Tigers pay for their wastefulness with them missing chance after chance to take the lead before that.
In another match, Home United defeated Courts Young Lions 2-0 with goals from Hafiz Rahim and Lee Kwan-woo.
